Mold Design

Main Stages of Tooling Design

Stage 1: Manufacturability and Feasibility
In this initial stage, design engineers, tooling engineers, materials engineers and manufacturing engineers work together to determine product specifications, mold component functionality, mold materials, operational constraints, and any needed product enhancements and improvements. The team especially looks for any potential problems in part geometry or tolerance that might result in poor steel conditions or require special tooling features such as lifters, slides, and threading/unthreading. The physical and chemical properties of the selected resin are also evaluated so that the proper mold steel can be selected and mold cooling be reviewed. Mold flow evaluation is also undertaken to determine the best type of gate and gate locations, in addition to determining proper vent locations.
Manufacturability review includes confirmation of standard plastic design practices and incorporation of tooling details to create the most robust design possible. Tooling specifications and tooling sources are finalized and purchased component sources qualified. A comprehensive process failure mode effects analysis (PFMEA) is also completed.

Stage 2: Design
Preliminary 2D and 3D design models are constructed to determine mold sides and steel sizes. Once these are reviewed and approved, the detailed design is finalized.

Stage 3: Final Design Specifications
The tool builder is given the tool design specifications for mold construction. Final adjustments and modifications are done in-house, with special attention given to manufacturability and critical dimensional requirements.

Stage 4: Bring the Tool In-House for the Initial Sample
A molding process is established that is acceptable to the manufacturing department. Processing parameters are recommended and established. Initial sampling using scientific molding practices is carried out; cavity pressure transducers in the mold accurately determine the filling profile over time. Sample parts are qualified.  

Stage 5: Make Any Final Tool Corrections 
Any needed process adjustments are made as required. Tool construction is verified and the process is detailed and documented so it can be used in the future with minimal setup time. Perfect parts are resampled and submitted to the customer. After final approval is obtained from the customer, the production process is launched.



High quality mold is based on excellent mold design, we have extensive experience in building different types of molds like:

      ◆ 2K Mold
      ◆ Over Mold
      ◆ Insert Mold   
      ◆ Stack Mold
      ◆ Hot runner Mold   
      ◆ Cold runner Mold                      
      ◆ Unscrewing Mold
      ◆ Prototype Mold



We will offer steel certification and heated treatment certification for full-hardened steel. Below are some of our steel suppliers as Uddeholm, ASSAB , LKM, BÖHLER, Gröditz,SSAB, FINKEL,SCHMOLZ-BICKENBACH,DAIDO, HITACHI .......



Almost all the molds are for overseas customers, so we choose mold components that easy to buy in different overseas country. Below are some of our components suppliers as HASCO, DME, Meusburger, DAIDO, CUMSA, LKM, MISUMI, PUNCH, PARKER, MERKEL, HP SYSTEM, Stäubli......



We know hot runner system is very important for the mold, so we know which kind of mold need which kind of hot runner system. Below are some of our hot runner system suppliers as HRS, HUSKY, MOLDMASER, INCOE, SYNVENTIVE, YUDO, männerGÜNTHER, THERMOPLAY, MASTIP, HOTSYS.......
